11. Frage
In NetAct's role-based access control model, which role would typically be assigned to a NOC engineer who needs to perform routine cell parameter and neighbor relation changes, but should NOT be able to modify user accounts or system-wide security settings?
Antwort: B
Begründung:
NetAct's role-based access control allows different roles to be granted permission sets aligned with job responsibilities. An 'Operator' role with CM provisioning privileges is scoped to perform day-to-day configuration tasks - such as modifying cell parameters, neighbor relations, or power settings - without holding the broader privileges of a System Administrator, who manages user accounts, security policy, and overall NetAct system configuration. A Guest or read-only user can view alarms, performance reports, and configuration data but cannot make changes, so this role would prevent the engineer from performing the required provisioning tasks at all. A Database Administrator role focuses on the underlying database infrastructure supporting NetAct rather than RAN configuration provisioning. Assigning an Operator role with CM privileges follows the least-privilege principle: the engineer receives exactly the access required to perform routine provisioning, and nothing more.
12. Frage
A NOC engineer 'acknowledges' an active alarm in NetAct FM. What does this action signify?
Antwort: C
Begründung:
Acknowledging an alarm in NetAct FM is an administrative action that marks the alarm as having been seen and taken ownership of by an engineer, without changing the underlying fault condition itself. In a NOC environment where multiple engineers or shifts monitor shared alarm lists, acknowledgement communicates that someone is already aware of and working on the issue, helping to avoid duplicated troubleshooting effort and providing a basic accountability trail for follow-up. It does not automatically resolve or repair the underlying fault - the alarm will only clear once the actual condition causing it is resolved, whether automatically by the network recovering or through engineer intervention. Acknowledgement also does not cause the base station to reboot, and acknowledged alarms remain visible in the active list (not deleted) until the underlying condition clears, at which point they typically move to the alarm history.
13. Frage
A NOC engineer is investigating subscriber complaints of being unable to access data services even though their devices show a strong 5G signal and successfully camp on the cell. Which KPI should the engineer examine first to determine whether the issue lies in establishing the data bearer itself?
Antwort: C
Begründung:
If a device successfully camps on a cell and shows strong signal levels but cannot access data services, the issue most likely lies beyond the initial radio connection - specifically in establishing the data bearer (PDU session in 5G, analogous to E-RAB in 4G) required to carry user-plane traffic to the core network. The PDU Session/E-RAB Setup Success Rate KPI directly measures how often these bearer establishment procedures succeed, and a low value points to problems such as core network signaling failures, transport issues toward the user-plane gateway, configuration mismatches, or resource allocation failures at the RAN. Cell Availability simply confirms the cell is operational, Handover Success Rate is only relevant once a session is active and mobility occurs, and strong RSRP only confirms good radio coverage - none of these directly explain a failure to establish the data session itself, making the PDU Session/E-RAB Setup Success Rate the correct first KPI to examine.
14. Frage
After a field engineer physically replaces a Remote Electrical Tilt (RET) antenna actuator, what remote verification should the NOC engineer perform to confirm the new unit is properly integrated?
Antwort: A
Begründung:
Remote Electrical Tilt (RET) units are Antenna Line Devices (ALDs) that communicate with the base station over the Antenna Interface Standards Group (AISG) bus. After a physical RET replacement, the appropriate remote verification is to confirm that the new device is discovered on the AISG bus, that it is communicating correctly with the base station's controller, and that its current tilt position can be read remotely and that tilt adjustment commands are correctly applied and reflected back. This confirms both the physical connectivity (cabling/bus communication) and functional operability (motor and position feedback) of the replaced unit.
The unit's color is irrelevant to functional verification, and while serial number changes are expected with replacement (a new unit will naturally have a different serial number, which should simply be recorded for inventory purposes), it is not itself a functional check. NR-ARFCN relates to radio carrier frequency configuration and has no relationship to RET device verification.
15. Frage
What does the NR-ARFCN (NR Absolute Radio Frequency Channel Number) represent in a 5G cell's configuration?
Antwort: D
Begründung:
The NR Absolute Radio Frequency Channel Number (NR-ARFCN) is a standardized numbering scheme defined for 5G NR that maps specific numeric values to corresponding carrier frequencies across the supported frequency range. When configuring a cell, the NR-ARFCN value (rather than specifying the frequency directly in MHz) is used to unambiguously identify the exact carrier frequency the cell will operate on, ensuring consistency across equipment from different vendors and alignment with regulatory frequency allocations. Correct NR-ARFCN configuration is essential for frequency planning, neighbor relation setup (since inter-frequency relations reference the target cell's frequency), and avoiding interference with adjacent operators or bands. This parameter is unrelated to subscriber database identifiers, alarm counts, or PRB utilization, all of which are tracked through entirely separate configuration management, fault management, or performance management mechanisms respectively.
